OIL CAN.

Application filed April 4,

on the oil can forming the subject matter of an application filed by me November 19th, 1927, Serial No. 234,401, the said oil can of the present invention embodying also new and novel features designed to promote efficiency in the oil can, the whole assemblage being designed to carry further in the direction of perfection an oil can of the general character forming the subject matter of my prior application referred to.

The nature of my invention and its distinguishing features and advantages will .more clearly appear as the description pro:

ceeds.

Reference is to be had to the accompanying drawing forming part of this specification it being understood that the drawings are merely illustrative of one example of the invention. I

Figure 1 is a vertical section of an oil can embodying my present invention;

Figure 2 is a horizontal section on the line 2-2 of Figure 1;

Figure 3 is an elevation of my oil can, the spout of the oil can being removed and the remaining elements entering into the oilcan being shown partly disassembled;

Figure 4 is an elevation of the oil can spout.

Referring to the parts of the invention represented in the illustrated example, a can body 10, usually cylindrical, and having a bottom 11, has secured to the bottom centrally thereof a plug 12 the reduced lower end of which plug is flanged over or upsetas at 13 againstthe under side of the bottom 11 to securely hold said plug in place. A packing ring 111 of cork or equivalent packing material ,is disposed on the bottom 11, which bottom is cup-shaped to extend about the cylindrical body 10 at the lower end. The packing ring 111 provides an arrangement forming a leak-proof joint between the cylindrical can body 10 and the bottom 11, and permits of making the parts of the pumping assemblage hereinafter referred to, quickly accessible that the entire bottom 11 can be'quickly removed from the body in a manner hereinafter referred to. The making of the cup-shaped bottom 11 removable as referred to enables the oil can to be made withless parts and at less cost:

1928. Serial No. 267,326. I

An assemblage comprising the filling neck and its cap 14in the present invention includes a filling neck15 which has a threaded zone 16.- Above the threaded zone 16 is a plain zone 17, the threaded zone 16 being adapted to be en aged bythe internal threaded zone 18-anl a plain zone 19 on the cap conforms to the plain zone 17 on the neck. The zone 17 constitutes a guide for the cap 14 and holds the cap in line in placlng the same on the neck so that the cap always starts straight on the threads 16 and makes it impossible to cross-thread the cap on the neck. This constitutes an important improvement as it is often necessary to remove the cap" to pour oil in the oiler when the weather is cold and when mittens or gloves are being worn by the user. Under these conditions it is very difficult tostart the ordinary cap straight on the threads of the filling neck, said threads in-praotice being formed both externally and internally, the present example showing the threads of the neck externally.

A packing ring 114 is'employed in practice in the cap 14 at the top seating on top of the neck 15.

The pumping assemblage of the present invention promotes simplicity of construc: tion and involves the minimum number of parts. The plug 1.2 has a polygonal surface 112 for convenience in holding with a wrench for assembling or disassembling the parts. Above the polygonal body 112 of plug 12 there rises a neck 20 having threads 120 which are engaged by corresponding threads on the lower end of a discharge tube 21 which extends from the said neck through the a top ofthe can body. The upper end of the discharge tube 21 is threaded and receives a nut 22, said nut having external threads 122 to receive a flanged nut or bonnet 23 the flange of which bonnet bears downwardly upon and serves to clamp against an annular shoulder 24 on the lower end of the nozzle 25 of the oil can to make the nozzle readily removable. 1

The neck 20 constitutesan oil chamber in which is a ball valve 26 controlling the flow of fluid into. said oil chamber through the bottom, inlet 27 thereof from the central chamber 28 of plug 12.- The ball check valve 26 is under pressure vof a spring 29,

and in the neck 20 is fitted astop 30 to be hereinafter referred to. a

ro'd'40 to prevent leakage.

Threaded into the plug 12 at oppositesides are tubes 31 and 32. At the outer end of the tube 31 is an oil inlet 33 controlled by a ball valve 34 or other check valve-underous application, said piston rod 40 extends upwardly through the can body top 43. Within the can body the piston rod 40 passes through the tapered housing 44 which abuts at one end against the can body top 43 and extends at its lower end to the piston 39. On the rod 40 at thetop 43 of the can is a felt washer 45 heldtightly against the top of the cover 43 and disposed about the Pressure is applied to the Washer 45 by a; spring 46 surrounding the projecting upper end of the plunger rod 40. An operating arm '47 is placed on the reduced upper end of rod 40 and held against displacement by a cap nut 48. I H

The numeral 50 indicates a handle on the can body at a side thereof.

Reverting to the stops 3O, 36,- each isd-isposed at that end of the springs 29, 35 farthest from the balls 26, 34. The stops 30 or 36 are essentially the same and are formed of a short strip of metal having the bend or protuberances 3 1, 51 projecting toward the ball valves 26', 34. In addition to taking the thrust of the springs at the end adjacent the bends 31, 51, said bend or protuberances 31, 51 constitute stops limiting the movement of the valves toward said stops so that the springs 29, 35 are always maintained with the convolutions' thereof open for the free flow of oil through the neck 20 and the tube It will be seen by a comparison of Figures 1 and 3 that a convenient mode ofa'ssembling or disassembling in the desired oil can may be practiced. Figure 3 shows that the bottom 11 has been detached from the lower end of the body 10 and as a unit with the bottom there is removed the element 12.; the fittings 31, 32, the pump cylinder 37 and the discharge pipe 21 as well as the valves in the element 31 and the neck 20 of element 12. On the other hand there is removed with the detachable top 43' the piston '31, its rod 40, the housing 44,- the spring 46 and the operat ing member 4Z together with the neck 15 and cap 14. The nut 22 is turned oil from I V the upper end of the discharge pipe 21 to permit" said discharge pipe being removed with the bottom 11'; If desired,- also, the

bonnet 23 may be detachable from the nut 22 to permit removal of nozzle 25 as shown in Figure 4.

I would state furthermore that While the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since manifest-1y, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

I claim: r v 1. An oil can including a can body open at the top and bottom, a bottom detachably held to the bottom of said body, a fitting permanently secured to the bottom, means forming an oil chamber and having an inlet, said means attached to said fitting,- a discharge tube held to said fitting to be removable with said fitting and the bottom, a pump cylinder supportedon said fitting to receive oil therefrom and to be detachable with said fitting and with said means, said discharge tube and the bottom as a unit, a detachable top on thebody, a piston operating in said cylinder, a piston rod connected with said piston and operatively associated with said top and removable and replaceable with the top, a capped filling neck held to the top to be removabletherewith, a nozzle, and means detachably connecting said nozzle with the discharge tube, the nozzle and the means' to connect the nozzle with the discharge tube being'removable with the top.
